1. GENERAL INFORMATION

1.1 Introduction. The DISKOS :3350, 6650 and 15450 use advanced Winchester and micro- processor technologies to provide users with low- cost disc drives having high capacity, fast access, and long-term reliability. Linear motor voice coil positioners with track following servos enable the DISKOS 3350, 6650 and 15450 to position Win- chester type heads quickly and precisely. These low-force heads assure high data reliability.

Advanced '14-inch Winchester-technology discs are driven by an outer-rotor, brush less DC motor.

The head positioner coil and carriage, heads and discs are enclosed in a sealed, contamination- resistant chamber to assure high reliability.

1

Two heads serve each disc surface, with one head and data band dedicated to servo information for fully servoed track following, head positioning and write timing. One disc recorded at 480 tracks per inch with three data bands is used in the DIS- KOS 3350 to provide a capacity of 34 megabytes of unformatted data. In the DISKOS 6650, one disc is recorded at 960 tracks per inch with three data bands to provide a capacity of 68 megabytes of unformatted data. In the DISKOS 15450, two discs are recorded at 960 tracks per inch with seven data bands to provide a capacity of 158 megabytes of unformatted data.

Microprocessors are used in the disc drive elec- tronics to provide interface flexibility and to moni- tor drive operation. For example, they control

308002 REV B

(7)

power up and down sequencing, and a self-test program checks drive performance during each power-up sequence. Any malfunction detected by tlhese tests will prevent drive start-up, reducing tlhe chance of loss o'f data or damage to the drive.

PRIAM disc drives are constructed in a modular fashion so that defective assemblies can be easily replaced. This greatly reduces down time due to servicing. The six assemblies are:

Head Disc Assembly Main PCB Assembly

Motor Control PCB Assembly Power Supply Module (Optional) Photocell Ass€!mbly

Frame Assembly

The Head Disc Assembly (HDA) is a sealed enclosure. It contains the drive spindle assembly, drive motor, voice coil motor, head carriage assembly, read/write heads, magnetic discs, and air filter assembly.

The Main PCB Assembly contains all the circuitr~

associated with read/write control, command exe- cution, information transfers through the user interface, processing servo signals from the servo read head, and controlling the position of the head carriage.

The Motor Control PCB Assembly contains the circuitry associated with driving the spindle motor. This circuitry receives an ON/OFF command from the main PCB, and spindle rotation feedback from the Photocell Assembly.

If the PRIAM power supply option is chosen, the power supply is mounted within the Frame As- sembly. The PRIAM power supply can operate from 50 or 60 HZ, with input voltage (selectable) of 1100, 120, 220, or 240 V /JIC.

The Photocell Assembly contains the photO-de- tectors which sense the DC Motor position. This information is used to control the electrical com- mutating required for brush less DC motors.

The Frame Assembly is constructed to accommo- date all optional assemblies of the disc drive. Its open steel rod and sheet metal design provides im- proved air circulation and makes the drive lighter, lower in cost and easiE~r to install.

"1.2 Options

"1.2.1 Interface Types. The PRIAM 14-inch disc drives are available with a variety of inter-

face options. All interfaces available from PRIAM include on-board data separation.

The standard PRIAM interface is designed for low cost and efficient use with micro-processor-based systems. Up to four drives may be daisy-chained when this interface is used. Tlhe PRIAM interface provides a basic a-bit bidirectional bus, which may be used with the popular a-bit and 16-bit microprocessors. It also provides bit-serial N RZ data exchange. No elaborate handshaking protocols are required. The PRIAM interface is built into the disc drive's main PCB. A 50-conductor flat ribbon cable is used between the PHIAM interface and the host system.

The SMD interface permits a PRIAM 14-inch drive to be used with existing Storage Module Drive (SMD) controllers. The SMD interface is embedded in the main PCB assembly and can be connected directly to an SMD controller. The line drivers and line receivers in the SMD interface are matched to those of typical SMD controllers. There are two interface cables between the host system and the drive interface - a 60-conductor twisted-pair flat cable ("A" cable) and a 26-conductor flat ribbon cable (" B"cable).

An ANSI interface adapter is also available. Char- acteristics of the ANSI interface include variable and fixed sector sizes,data transfer rates up to 10 megabits per second, and radial attention and select capability. Up to eight dlrives may be daisy- chained on a single 50-conductor flat ribbon cable.

1.2.2 Interface Cables and 'Terminators. I/O cables are available from PRIAM for con- necting daisy-chained drives to one another.

Terminators are available for I/O Signal lines to minimize reflections and to ensure maximum data integrity. One terminator is r1equired for a single drive or for the last drive in a daisy chain. Each drive is shipped with a terminator installed.

1.2.3 Power Supplies. PRIAM's optional power supply allows PRIAM elisc drives to operate from 100, 120,220, and 240 VAC, 50 or 60 Hz power.

The optional power supply iis delivered already mounted within the drive frame. No extra space or interconnection is required.

1.2.4 Mounting Hardware. Optional sl ides are available from PRIAM .. These slides allow easy access to drives mounjted in standard 19"

racks and cabinets.

Grasp the hand holes at each end of the drive's cardboard wrapping and carefully lift drive out of the inner carton.

CAUTION

The weight of the drive is substantial and if drop- ped can cause severe damage to the Head/Disk Assembly, which will not be covered under warranty.

Place the drive on a clean, flat surface and remove the protective cardboard and polyethylene wrap.

Retain the shipping container for any future ship- ments of the drive.

3.2.3 Inspection Procedures. After unpacking the disc drive, inspect it thoroughly for damage hidden by the packagin~J and for loose components or fittings, as follows:

a. Inspect the interior for shipping damage.

b. Examine internally mounted components for loose or misSing hardware.

c. Tighten all loose hardware.

d. Clean the frame interior by removing loose debris.

e. Check that head and spindle locks are secure.

3.3 Handling Procedures

3.3.1 Shock and Vibration Precautions. The drives must be handled in a manner as not to, exceed the Non-Operational Shock and Vibra- tion limits specified in Table 2.2.

3.3.2 Spindle and Head Locks. Both the drive spindle and the head carriage are locked at the factory prior to shipment. After the drive has been positioned for bench testing or installed in the final system, the spindle and head carriage locks must be set in the "Unlock" position to allow normal operation. Both locks are located on the bottom of the H DA (Head Disc Assembly). See Figure 3-2.

3.3.3 Drive Handling C3uidelines. Adhere to the steps outlined in Table 3-1 when handling drives.

Table 3-1. Winchester Disk Drive Handling Guidelines (unpacked)

• Always lock spindle/carriage whenever drive is moved. (Do not try to lock while drive is spin- ning.)

• Do not drop drive from any height. Drive should be laid down carefully.

• Carts used for transporting drives should have soft rubber wheels to absorb shock.

• Drive should be stored or transported in a vertical position with lon~~ dimension horizontal or flat, top up, and drive motor down. Drive must be on a flat surface. Do not put papers, etc. under drive"

• Only unlock spindle when drive is in normal operating attitude.

• Do not apply power when spindle is locked.

• Do not dress or re-position components, wires or cables.

• Do not place drives in vertical position closer than 2-3 inches apart to avoid hitting and break- ing components.

.' Avoid manual rotation of the spindle or move- ment of the carriage. Damage to the disc surface may occur if the heads are moved across a non- rotating disc surface.

.' Do not remove plugs from HDA assembly. This may result in contamination which may affect drive operation. Do not attempt to disassemble HDA.

.' Do not lay objects on top of drive, espeCially metallic objects.

Shipping Requirements.

3.4.1 Spindle and Carriage Locks. Before packaging a drive for shipment, it is necessary to secure the spindle and carriage locks. (See Fig- ure 3.2.) A sequence down operation must be per- formed before the drivle can be removed from the system and the locks are engaged. After the spindle has come to a complete stop, engage the spindle lock to clamp the 'fan blades. Also, move the head carriage lock to tl1e "Locked" position since the heads should be retracted into the landing ,zone by the previous sequence down operation. If

the head lock lever cannot be~ engaged fully Do Not Force. Instead, return the lever to the unlocked position, tilt the drive so that the round VCM assembly pOints downward and then return the carriage lock to the locked position.

3.4.2 Shipping A Stand-Alone Unit. After the drive is removed from the system (with the spindle and carriage locks secure), the drive must be packaged to withstand the environmental ex- tremes specified in Table 2-2. Use of the original PRIAM shipping container is recommended. A user designed shipping container may be substi- tuted if it meets or exceeds the PRIAM non-operating environmental specifications.

NOTE: Failure to ship the drive in a proper container will void its warranty.

Important! Remove slides, brackets, parts of en- closures and cabhes from the drive before plaCing it in the shipping container.

3.4.3 Shipping Drive Mount.~d in an Enclosure.

When shipping the drivE~ while it is installed in a system, all environmental specifications in Table 2-2 must be adhered to. Vibrations around 50 Hz should be carefully checked when shipping drives in large mainframe systems, as they can cause the drive to resonate! on its protective shock mounts. If the system ()r enclosure cannot be packaged for shipment so that the drives will meet the specifications in Section 2.2, it is recommended that the drive(s) be removed from the system or enclosure prior to shipment and shipped as a stand-alone unit. (See Section 3.4.2.)

3.5 Functional Testing. The following functional test is a recommended test for in- coming receiving inspection to insure that the drive is operational and that riO shipping damage . has occurred.

Time Test

1. 1 min. Power up drive and get ROY.

2. 15 sec. Perform max. length seeks.

3. 15 sec. Perform random seeks.

4. * Format, if applicable.

5. 1-3 min. Sequentially write all cylinders and all heads with worst case pattern. (924 ••. , 249 ••• , 492 .•• ) 6. 1-3 min. Sequentially rea.d what was written.

7. 1 min. Random Write and Read.

* Time dependent on size of drive and formatter used.

4. PRIAM INTERFACE OPERAITION

This section provides information for setting up all 14-inch drives having a PRIAM Interface for use in an OEM system. This includes power selection, jumper and switch settings, interface signal definitions and other information to insure proper system operation.

4.1 Mounting. All PRIAM 14-inch drives can be mounted in a standard 19-inc:h rack. PRIAM offers an optional slide mounting kit for use with the 14-inch drive models. See Figure 2-1 for mounting dimensions.

4.2 Power Supply Setup. If a PIRIAM optional power supply is used, check the AC voltage selection circuit board prior to applying power.

This board is adjacent to the AC input plug, and is an integral part of the power supply. To select a voltage, remove the selection circuit board and re- insert it so that the proper AC voltage designation (100, 120, 220, or 240) is visible. Also check the fuse value. A 5-amp fuse is used with 100 or 120 VAC operation, while a 2.5-amp fuse is used with 220 or 240 VAC operation. No modification is required for changing between 60 Hz and 50 Hz power.

4.3 Switch Settings. The drive address, write protect parameters, and sector size are all switch selectable. The switches are located on the main PCB. Referring to Table 4-1, set the switches according to the desired operating conditions for the applicable Model Drive. See Figures 4-1, 4-2 and 4-5 for the locations of the applicable DIP switches.

4.4 Jumper Settings. Jumpers are black con·

ductive tabs that can be inserted on board pins to complete a particular circuit. Although most of these are used only at the factory to facili·

tate testing, some have user selectable functions.

It is important that all jumpers be installed in their proper locations. See Figures 4-1 to 4-6.

Refer to Table 4.2 for jumper position to enable the correct operating conditions for the application.

4.5 Cabling Requirements. All drive signal connections are made via a single 50-pin ribbon cable connector. A second 50-pin connector is available on the main PCB for daisy chaining to another drive or for a terminator for the last drive in the string. Up to four drives may be daisy chained.

A separate connector for DC powE~r is provided. If the optional power supply is installed, then its output is connected to this DC power connector and AC power must be supplied to the optional power supply.

An 8 pin DIP socket for remote write protect con-

trol~ fault clearing and drive status is also provided on the Main PCB.

3. - RD. This low-active signal is used to gate the contents of the selected register (decode of AD1 and ADO) onto the DBUS. This line is connected to a 74LS2244, gated by DR:IVE SELECTED, as shown in Figure 4-11. The DC characteristics are listed in Table 4-8. This line should be terminated at the drive end.

4. - WR. This low-active signal is used to gate the DBUS into the selected register (decode of AD1 and ADO). This line is connected to a 74LS244, gated by DRIVE SELECTED, as shown in Figure 4-11. The DC characteristics are listed in Table 4-8. This line should be terminated at the drive end.

5. - RESET. This low-active signal resets the drive logic. If the drive is sequenced down when RESET occurs, it will remain sequenced down. If the drive is sequenced up, it will remain sequenced up and the head carriage will restore to cylinder zero. This line is connected to a 74LS244, gated by DRIVE SELECTED, as shown in Figure 4-11. The DC characteristics are listed in Table 4-8. This line should be terminated at the drive end.

6. - WRITE GA TE. This low-active signal enables the writing of data by a selected head. This line is connected to a 74LS244, as shown in Figure 4-11.

The DC characteristics are listed in Table 4-8.

This line should be terminated at the drive end.

7. - READ GATE. This low-active signal initiates synchronization of the drive's variable frequency oscillator for data separation. READ GATE must be enabled during a gap. This line is connected to a 74LS244, as shown in Figure 4-11. The DC characteristics are listed in Table 4-8. This line should be terminated at the drive end.
